Thanks. The flickering might just be one PCB then, but I'll investigate more. And freezes could relate to the newer kernel versions then.

I don't remember having any of those, but that was some time ago. Not sure about the keymap, but the heavy flickering and the freeze at powersaving: I don't think I had that.

Hi,

just a few quick questions to everyone who has a prototype. Before I
file a bug, I wanted to check if others can confirm this as well.

I'm using aTc's OS.

1. . - Key (the left one on the lower row) is not working. Happens with
multiple Mainboards - keymat looks fine (but I haven't changed it yet).
Softwarebug?

May be a problem in the keymap. The kernel driver reports the command and dot keys.

2. Sometimes, I encounter heavy flickering of the LCD. Especially
shortly after boot up. This looks like displays backlight power
completely breaks down.

Hm. May be a problem with display cable (connector).
